This can be a higher-level question for those who haven’t exposed the mobile application testing with different technologies. However, you can answer this question simply by telling the interviewer about the following practices which are common
The very first one is storing the test cases together with the source code. The next one is assuring that the rooted devices (devices on which a customized OS has been installed as Android is an open source technology) should be avoided. The third one is to build the test cases at the same time when the codes are written by the developer and the fourth one which is rare is making use of continuous integration and executing the test whenever there is a change in the code is noticed.
